This invention relates to a threadguide and also to a combined; thread guide and traverse bar to be used on winding machines orother machines asdesired, the object being '5 to present a struoturewhich may be easily adjusted and which will hold a thread cleaner as the thread is guided to a winding bobbin.

Another object of the invention is to pro: vide-a thread guide adapted to be removably mounted on; a traverse bar with. the parts so arranged thatthe guide will be tilted in order that the thread may move vertically V upwardly .and engage a. rounded guiding groovejwhen contacting with the traverse 1513 5 further: objectof the invention is to provide a thread guide having a guiding porcelain and a bracket, the porcelain having a base or bottom surface at such anangle as '20 to cause the porcelain to be inclined when mounted on a' horizontal surface, the bracket being correspondingly formed to firmly. hold the porcelain on a traversebar or other sup port whilepermitting the same to be quickly removed at any time. 7 c i In the accompanying drawing,

Figure 4: is a sectional view through Figure 1 on line 4-4.

Figure 5 is a detailed perspective view of the bracket shown in Figure 3.

Referring to the accompanying drawing by numerals, 1 indicates a traverse bar provided with a longitudinally positioned slot 2 for receiving the base 3 of the bracket 4. This bracket is adapted to receive a guiding porcelain 5 and hold the same firmly on the traverse bar 1. In cleaning and winding machines, a traverse bar is used similar to traverse bar 1 and a number of guides are arranged thereon so that a number of threads may be cleaned and wound at the same time. In the present invention, the guide is .in

tended particularly for machines of this'kind and consequently porcelain 5 carries a, cleaner 6:.Wl1l0l1 is,; generally speaking, two ream gular pieces o'f,.metal [clamped together by a suitable clamping screw but held slightly apart by a shim 7' whereby a slot 8 Will be presented through which thethread 9 passes. This *cleaner isadapted ,t'owc'lean any protuberance's or enlargements frOnifthe thread so that after the thread passestherethrough it will be of a desired size. The use of cleaners of this kind. is old and well known and'there-i fore. this cleaner forms no part of the present invention. except in combination. Heretofore,.various form's; ofholders have been provided for the, cleaners, said holders acting as guides for guiding thethread to the cleaners.

It will beevident that a thread even' though it may be silk, will wear any. surface over which it rubsand consequentlyin the present invention, the guide has been made from porcelain vandprovided with, a rounded edge-9 over which the -'thread passes tol' the' take-up bobbin. Porcelainf5, asillustrated in the drawing, isprovided, withv side'grooves 10 'andll and a central notch .12. 1 Central grooves'13 and 14. areprovided for accommodating the cleaner 6 so that the slot or opening8-will be positioned substantially centrally. of the, notch {12 as illustrated in Figure 1. Thegrooves 1O and'll accommodate the-arms 15 and 16 of "the bracketf l and .the porcelain. 5 is V rigidly" connected j with the bracket through the action of screw 17. This screw is positioned with its head in an :anerturefl8 in porcelain 5, as shown in Figure 45, while the body or, this. screw is screwed into'a threaded aperture in the arm 15 for positively locking the bracket and porcelain together. f

The base 3 of the bracket is provided with a slotg -l9 throughwhich theclamping screw .19" eXtend s. Said clamping screw 'is' shown .as a boltand extends through the 'traverse .barl a's illustrated in dotted lines on Fig- Fure 2, thus clamping the-bra'cket l in place. By reason of the slot'19, thebracket may be adjusted longitudinally of the traverse bar. As illustrated in Figure 2, the bottom surface20 of the p'orc-elainl5 is positioned at 100 such an angle to the side surface of the porcelain that the entire porcelain will incline sufficiently to cause the thread 9 to be held out of contact With any part of the machine until it passes over the curved surface 9. It will thus be seen that the device includes the holding bracket 4 and the porcelain guide 5. b
